10 Claims.

This invention relates to beds in general and more especially to combination single, double and twin couch beds.

Among the objects of the present invention, it is aimed to provide an improved combination single and double couch bed having a main bed frame, an extension bed frame, and independent mattress or upholstered portions in which the main bed frame is frictionally anchored against movement and has a bed spring spaced from the floor to form a chamber, the extension bed frame is mounted on rollers, has a bed spring and is adapted to be moved under the bed spring of said main bed frame in single bed formation and is adapted to be moved outwardly, adjoining said main bed frame in double bed formation and in which there is provided a sideboard along the longitudinal free edge of said extension bed frame between which and the back of the main bed frame there are disposed alongside of one another mattress or upholstered portions in double bed formation.

It is still another object of the present invention to provide a combination single and double .couch bed in which two independent'mattress or upholstered portions are disposed alongside of one another between the back of the main frame and the front board of the extension bed frame temporarily to anchor the two bed frames in double bed formation. It is still another object of the present invention to provide an improved combination single and double couch bed having a main bed frame, an intermediate carriage connected to said main bed frame by collapsible bars, and an extensible bed frame connected to said carriage, the outward movement of the carriage and extensible bed frame being determined by said bars in extended position where said extensible bed frame is disposed adjacent to said main frame, and mattress or upholstered members being disposed between the back of said main frame and the end board of said extensible bed frame to anchor said extensible bed frame against accidental movement under said main frame.

It is still another object of the present invention to provide an improved equalizer or guide for guiding the extensible bed frame into and out of extended position relative to a main bed frame.

It is still another object of the present invention to provide an improved temporary connection between the extensible bed frame and a supporting carriage operatively connected to a main bed frame by means of which connection the extensible bed frame can with facility be liberated to form an independent twin bed movable to any remote distance from said main bed frame.

It is still another object of the present invention to provide an improved combination single, double and twin couch bed which can be manufactured at low cost, which has a small number of operating parts and which can be operated with facility by the average housewife unskilled in mechanical movements.

Fig. 10 is an enlarged transverse section of said second embodiment in single bed formation; and

Fig. 11 is a side or front elevation of the extension bed section of said second embodiment in raised position.

In. the embodiment shown in Figs. 1 to 8, there is illustrated a metal frame constituting the main bed section I connected to a couch forming structure having an upholstered back 2, and arm embracing side wall members 3 and 4 which structure is preferably supported on rollerless feet 5 and 6 to form a substantial frictional en gagement with the supporting floor.

The bed section I embraces generally a rectangular frame 'I supporting a flat bed spring 8, rear downwardly extending supports 9 which preferably as illustrated do not extend to the supporting floor and a bar I extending from one support 9 to the other at a short distance below the level of the bed spring 8. The bar I0 preferably consists of an angle iron having a longitudinally extending flange I I provided with a recess I2 formed therein to receive the stud I3 connected to the elongated link I4. Pivotally connected to the flange II at one corner thereof is another elongated link I5 preferably corresponding in length to link I4. At the other end of the flange I I, there is pivotally connected one end of a short link I 6 the other end of which is pivotally connected substantially at the middle of the elongated link I4. The links I4 and I5 are preferably arranged to move while in parallel relation to one another and their forward free ends are connected to the horizontally extending flange I! of the crosspiece I8 of the intermediate carriage I9 constituting an auxiliary member for supporting theextension bed section when moving such extension bed section into and out of double bed formation.

This flange I! has an elongated slot corresponding in length to the slot I2 in the flange II and has slidably mounted therein a stud 2I formed at the end of the link I5. One end of the flange I! has pivotally connected thereto the front end of the link I4. The other end of the flange I I has pivotally connected thereto one end of the short link 22 which has its other end pivotally connected substantially to the middle of the elongated link I5. The short link 22 is adapted to move in parallel relation to the short link I6 so that the links I4, I5, I6 and 22 together with the flanges I I and I! will effect a parallel movement throughout. In other words, the flange I I of the carriage I 9 will be maintained in parallel relation to the flange I I whether in extended position as illustrated in Fig. 3 or in collapsed position as illustrated in Fig. '7 and' out of exfacility be maintained in an upright position without any additional supporting means. The carriage I9 will of course be supported by the rollers 25 and 26 to be moved into and out of extended position on the rollers 25 and 26.

The front bar 21 of the rectangular frame I consisting of an angle iron preferably has its vertically extending flange 28 extending upwardly from the flange 29, see particularly Figs. 2 and 5 and in such position this flange 28 acts as a limiting stop for the mattress or upholstered member 39 when the main bed section I is used as a twin bed independent and separated from the extension bed section.

The frame I is preferably mounted at a level above the supporting floor to form a chamber to receive the extension bed section 3| without its mattress or upholstered member 32. The extension bed section 3| embraces essentially a rectangular frame 33 for supporting a flat spring 34, and has a front board 35 extending vertically along its front bar 36 which board 35 is preferably covered with upholstery 31 as indicated in Fig. 6.

The board 35 extends both above and below the level of the frame 33 to correspond with and complete the design of the lateral extensions 38 of the side wall members 3 and 4 when the extension bed section 3| is moved into single bed formation, that illustrated in Fig. 1.

The extension bed section 3| when separated from the main bed section I as an independent twin bed, is movably mounted upon rollers or casters. Adjacent the front board 35 and extending downwardly from the side bars 39 and 49 of the frame 33 there are provided the brackets 4I having journaled at their lower ends the larger casters or rollers 42. Extending downwardly from these two bars 39 and 49 adjacent to the rear end of the frame 33 there are provided the brackets 43 having journaled at their lower ends the small rollers 45. The brackets 43, see particularly Fig. 8, have angle irons 46 provided with rearwardly horizontally extending flanges 41 disposed at a level below the bed spring 34 and provided with orifices 48.

These orifices 48 are adapted to receive the rounded heads 49 extending upwardly from the flange IT of the carriage member I9. For convenience of construction, these heads 49 are formed on the pivot pins connecting the links 22 and I4 to the flange II.

In single bed formation, the mattress or upholstered portions and 32 are preferably mounted one above the other as illustrated in Fig. 1 from which it will also appear that the upholstered portion 32 is preferably wider than the upholstered portion 39 and overlaps the front edge of the upholstered portion 30 to register with the front face of the upholstered portion 31 of the board to complete the upholstered design of the couch.

In this single bed formation, the extension bed section 3! connected by the cooperation of the orifices 48 with the studs 49 will of course be disposed uncler theframe I of the main bed section I and the carriage I 9 will be disposed adjacent to the rear wall of the couch with the links 22, I5, I4 and I6 collapsed or in folded position as indicated in Fig. 7.

When it is desired to convert the couch bed from single bed formation to double bed formation, it will only be necessary to engage the end board 35 and move it outwardly into the position illustrated in Fig. 2 and then remove the mattress or upholstered portion 32 into the space formed between the end board 35 and the mattress or upholstered member 30. When the mattress 32 is so positioned it will as indicated form a block or obstacle to prevent the inward movement of the extension bed section and thus. anchor the same against accidental movement under the main bed section.

Preferably the mattress member 32 may have a couch covering on one face thereof to face outwardly when the mattress member 32 is disposed on the mattress member 30 in couch bed formation or disposed so that its couch covering will face downwardly in single bed formation. Similarly when the mattress member 32 is mounted on the extension bed section for double bed formation, the couch covering face will preferably bedisposed to face downwardly with the mattress covering facing upwardly.

The links 22, I 5, I4 and [5 as aforesaid will serve by cooperation with the slots l2 and 20 not only to limit the outward movement of the extension bed section, that is predetermine its outward position in double bed formation but will also serve to guide the extension bed section in a predetermined parallel movement relative to the sides 3 and 4 and back 2 of the couch.

From the foregoing, it will also appear that when the extension bed section is moved into double bed formation, it will be mounted to ride outwardly on the rollers 25, 26 and 42 with the rollers 45 elevated above the supporting floor as indicated in Fig. 2.

, When it is desired to convert this device into two independent twin beds, it is only necessary to remove the extension bed section 3i from its connection with the carriage [9, that is by raising the brackets ll to clear the studs 69 and then permit the extension bed section to be moved outwardly upon the rollers 45 and 52. Thereafter the mattress member 32 may be positioned on the frame of the extension bed section M as heretofore explained when it will form an independent twin bed as shown in Fig. 6 independent of the twin bed formed by the main bed section I. On the other hand of course the twin bed conversion may also take place after theextension bed section has been moved outwardly with the carriage ii] in whichcase the extension bed section 3i will be separated from the carriage H! as heretofore explained by raising the one end of the extension bed section to permit its brackets Al to clear the studs iii.

When the extension bed section forms a twin bed, it will of course be mounted as illustrated in Fig. 6 on the rollers 45 and 42. After the bed sections have been separated into twin bed formation. and it is then desired to convert it into single bed formation, it will be only necessary to remove the mattress member 32, place it on the mattress member 30, connect the extension bed section to the carriage It by lifting the rear end of the same so that the orifices =38 of its brackets 47 will receive the studs 43 and then press the extension bed section inwardly into the chamber formed below the frame I.

As illustrated in Fig. 2, the mattress 32 is also deeper than the mattress 30 sothat when this mattress 32 is disposed on the extension bed section 3| in double bed formation, the upper faces of the mattresses 30 and 32 will be in alinement with one another;

Preferably to prevent the accidental displacement of the extension bed section when disposed in single bed formation, a suitable latch is provided, such for instance as the upwardly turned flange 36" secured to the front bar 3% of the extension bed section 3i having an outer cam face to strike the nose of the latch bar 2'6" pivotally connected to the vertically extending flange of the front bar 2'! of the frame I and having its nose extend down through an opening formed in the horizontal flange of said front bar 21 and into the path of movement of the upper cam face of the flange 33 when the extension bed section is moved inwardly.

In order to release the extension bed frame from the latch bar 21', it will only be necessary to pass the hand between the mattress and the front board 31 to'raise the latch bar 27 and thereupon exercise an outward pressure on the extension bed section 3-1.

In the embodiment illustrated in Fig. 9, the main bed section 50 is substantially identical to the main bed section l of Fig. 1 except that it is made according to the studio bed type and thus is not provided with a back and arms such as the back 2 and arms 3 and 4 of the main bed section I.

The extension bed section 5| on the other hand instead of having a fixed upper level as is the case with the extension bed section 3| of the embodiment illustrated in Fig. 1, has a vertically movable upper frame member 52. Otherwise the extension bed sections 5i and M are substantially identical.

In this second embodiment there are provided two frames, to wit the upper frame 52 and lower frame 53. The lower frame is substantially rectangular having two end angle irons 54 and two longitudinally extending or side angle irons 55 and 56, the angle iron 56 being disposed at the front face of the extension bed section. 5! and has secured to the vertically extending flange the facing board 5'! which extends the full length of the front face of the extension bed section 5i and also extends from a level below the lower face of the angle iron 55 to a level, see Figs. 9 and 10, where it will just clear the lower face of the upper front facing board 58 of the main bed section 58.

The lower frame 53 is mounted on rollers having secured to and extending down from the horizontally extending flanges of the end bars 54 adjacent to the angle iron 56 the brackets 59 to which the large rollers 60 are journaled. To the outer faceof the vertically extending flange of 7 The upper frame 52 is similarly substantially rectangular having the end angle iron 6? and the longitudinally extending side angle irons B8 and 69. Corresponding ends of the upper and lower frames 52 and 53 are connected to one another by the sets of cross bars l8 and i I. The upper end of a cross bar iii in the present instance is pivotally connected to the vertically extending flange of a side bar 61 and the lower end of such cross bar is provided with a pin 12 slidably mounted in the slot it formed in the vertically extending flange of a side bar E l. The cross bar ii on the other hand has its lower end pivotally connected to the vertically extending flange of a side bar 54 and its upper end provided with a pin 54 slidably mounted in the slot '15 formed in the vertically extending flange of the side bar 61. The cross bars lo and H of each set are pivotally connected to one another to form a. cross in expanded position, that shown in Fig. 9.

The pin it for pivotally connecting the bars 7i] and H to one another is preferably pivotally connected to the lifting bar I! which is provided with a pin 18 at its lower end slidably mounted in the slot 19 formed in the vertically extending flange 'of a side bar 5 1. ,To cooperate with the cross bars IG and H to form a stabilizer, there is in the present instance provided a lever 86 and link 8!, the lever 86 being pivotally connected at its lower end to the vertically extending flange of the bar 56 and provided with a pin 82 at its upper end to slide in the slot 83 formed in the vertically extending flange of the angle iron 69. The link 8| on the other hand is pivotally connected at its lower end to the middle of the lever 80 and at its upper end is pivotally connected to the vertically extending flange of the angle iron 69.

For connecting the extension bed section 5| to the main bed section 50, there is provided an intermediate carriage l9 constituting an auxiliary member for supporting the extension bed section 5|] while moving into and out of double bed formation, substantially identical to the carriage [9 of the embodiment illustrated in Fig. 1, which carriage I9 is similarly provided with a stud 49. This carriage I9 is also connected to the main bed section 50 by linkage similar to the linkage I5, 22, and l4, N5 of the embodiment illustrated in Fig. 1 only one set being shown in the present instance, to wit the set [4, I6.
